Hi list, Any body is aware of SMTC support status in latest git sources?. I have tried testing SMTC kernel for malta in qemu / OVP without any success ( emulators not working for 34k). I am trying to bring up SMTC Linux support for an mips34K based soc ( MSP71xx family). While booting , kernel getting hung on calibrate loop delay. I am getting only one interrupt from timer. With similar smtc platform support file ( changed to map smp_ops structure) 2.6.24-stable branch kernel ( where latest timer structure introduced) boots fine.
